1. Introduction

1.1 Background

South Korea,officially the Republic of Korea is a country in East Asia,consisting the southern part of the Korean Peninsula,and sharing a land border with North Korea.About 25 million people,around half of the country’s population of 51 million,live in the Seoul Capital Area.

South Korea is a developed country and rank as the seventh-highest country on the Human Development Index(HDI) in the Asia-Pacific region.It is a member of OECD’s Development Assistance Committee,the G20 and the Paris Club.Its economy ranks as the world’s tenth-largest by nominal GDP.

South Korea’s health system is centered on hospital-based care.The number of hospital beds per capita 12, beds per 1000 population,is two times higher than the average in Organization of Economic Cooperation and Development(OECD) countries.The country excels not only in hospital capacity but also in interactions with doctors,with an OECD-leading 16.6 consultations annually per capita.Although some critics suggest that South Korea’s health system is overly dependent on secondary or tertiary facilities instead of primary facilities,this extra capacity enabled hospitals to respond quickly to COVID-19 without sacrificing care for non-COVID-19 patients.

1.2 Visualization of the location

1.3 Climate condition

Unlike many other Asian destinations, South Korean weather is fairly straightforward and easy to understand. There are only minimal regional variations throughout the country, and the year divides neatly into four distinct seasons.

  1. Spring - Typically lasting from April to June, with average daily temperatures a pleasant 15 - 18°C.

  2. Summer - The brief summer lasts from July to August and is the hottest time of the year in South Korea. Temperatures may range between 23°C and 30°C but this is also the wettest time of the year, with the monsoon rains bringing half of the country’s annual rainfall during these months.

  3. Autumn - (September~November) is the best time of A year in south Korea.The weather will be cooler and dryer, but it will be still sunny and warm.

  4. Winter - Falling between December and March, the long winter is freezing cold but relatively dry, and certainly charming.

The first domestic confirmed case of the coronavirus disease (COVID-19) was identified in the Republic of Korea on 20 January 2020. By 16 February, 30 new confirmed cases due to foreign inflows or local community transmission had been identified, the route of infection was not traceable for all these cases. On 17 February, the 31st confirmed person (later named as a “super-communicator”) was diagnosed in Daegu City. A full-scale epidemiological investigation started for the believers of a religious sect in Daegu where the supercommunicator belonged to. Multiple confirmed cases related to super-communicator, and first death occurred in 20 February. The number of confirmed cases continued to increase thereafter, resulting in up to 1,062 cases per day (2 March). On 6 April, although the number of new confirmed cases decreased to fewer than 50 (47) per day, many cases of group infection occurred mainly in entertainment facilities during the holiday season starting on 30 April. On 12 August, as a confirmed case occurred in a church in Seoul, the number of related confirmed patients, including visitors, prayers, and family members of the churchgoers, increased to about 200 in 4 days. As a large number of confirmed patients occurred in the greater metropolitan area of Seoul, the government upgraded social distancing level to the second stage only in the capital area, but the number of confirmed cases per day remained in the hundreds. On 20 September, the number of new confirmed cases per day again declined to fewer than 100 people, and showed a decreasing trend compared to August. However, because of concerns that the number of confirmed cases may increase again starting from the major holiday (Thanksgiving Day) scheduled from 30 September to 4 October, the disease control authorities monitored the trend without lowering the level of quarantine stage.

• First confirmation : 20 January 2020

• Cumulative confirmation: 23,611 (as of 27 September 2020)

• Cumulative deaths : 401 (as of 27 September 2020)

• Fatality rate : 1.70% (as of 27 September 2020)

1.4 Government Action for COVID-19

The Republic of Korea’s response to COVID-19 has been among the most effective in the world. By combining aggressive testing with early isolation and treatment of those who test positive, Korea has lowered its infection rate while avoiding the need to lock down entire cities. The government reorganized hospitals to prevent infection, effectively distributed face masks and will cover all COVID-related medical costs. After peaking at about 800 new cases per day in March, Korea had only 14 on April 28.

The data of coronavirus in south korea was collected from 2020-01-22 to 2021-09-18. In here number of minimum recovered cases reported as -17.This gives the incorrect information because cases can not be negative value.so this can be a outlier for our data. Therefore for we can replace it as missing value.And here there are 45 NA’s.
